Sure it will. We aren't the first creatures or even people to witness what we take to be the end of the world. You can grieve it and do your best to resist it if you so feel called. If you can do so out of love for whatever it is that you value. My gratitude and respect if so.
Just stop believing that it is "bad". Which is NOT the same as saying it's "good". It's just the natural consequence of everything that has happened so far. Or do you shake your fist at the meteor that wiped out the dinosaurs? Have you given a good talking to at the volcanoes in Siberia for wiping out nearly all life in the Great Dying? Or any number of other events that led to mass extinctions. Human nature is also just a natural consequence and we're a microscopic blip in Earth's history. Cherish what is here now and do what you're called to do out of love for what you want to protect but you'll spare yourself a lot of meta-suffering if you can give up the idea that there's some right or wrong way for history to go. There's just what is advantageous for humanity and what isn't. I'm aligned with the former but I don't believe that humanity should or shouldn't exist.
